1. Field of the Invention
The present invention is in the field of computer mass storage devices, and pertains more particularly to solid-state USB connectable drives.
2. Discussion of the State of the Art
In the computer arts there continues to be motivation for increased density and ease-of-use in mass storage devices. A solid state device known now in the art as a thumb drive was relatively recently introduced advancing the standard for both density and ease-of-use, and such hot-plug drives are made by several manufacturers. A common feature of thumb drives as known in the art is a male USB connector, and functionality to hot-plug and remove, that is, without turning off the computer to which the drive is connected and disconnected. Another common feature is a plastic protective cover for the male USB connector.
Although the advance in the mass storage art with the advent of thumb drives is dramatic, there are still some problems with such a system. For example, the plastic covers for use on the male USB connectors are not very secure, and tend to come loose and be lost. As a remedy, many manufacturers provide two and sometimes three plastic covers with each device sold, often with different colors. Still another problem is that USB ports on computers are not universally easily visible and accessible. Some such ports are on the back of tower cases which are often placed under desks or other furniture, so finding an unused USB female port for connecting the male USB connector of a thumb drive is often not trivial. When a female port is out of sight or in a darkened area, the connection must often be made by feel alone. Still further, when the thumb drive is connected to a computer, the plastic protective cover is removed, and is easily misplaced.
There are also other functions that may be accomplished with the considerable memory available with thumb drives, and their relatively easy connectivity to personal computers and other computerized appliances. One such function is as an MP3 player, to download MP3 files, such as music files, from a computerized appliance, and an ability to play these files into an ear piece, headphone or amplifier from the thumb drive.
Therefore what is clearly needed is a way to dispense with the plastic covers and still protect the male USB connector for thumb drives, a way to aid in the search for unused USB ports, and aid in the engagement of the male USB connector of the thumb drive with the female port on the computer, and a way to use the thumb drive as an MP3 player.
In one embodiment a thumb drive is provided, comprising an elongated housing enclosing an assembly of a coupled memory and male USB connector constrained on a translation mechanism in the direction of the long dimension of the housing, with an opening at a first end of the housing through which the male USB connector may extend and retract, a top cover engaged in tracks and translatable in the long direction of the housing, and gears rotating on a shaft across the housing and engaging a gear rack along edges of the top cover and along upper edges of the memory and connector assembly. Translating the top cover forward retracts the connector into the housing, and translating the top cover rearward extends the connector from the housing.
Also in one embodiment the thumb drive further comprising a film cover for the opening for the connector, the film cover attached to the top cover to extend to close the opening as the top cover translates forward, and to retract to open the opening as the top cover translates rearward.
In some embodiments there is also a fixed panel closing the housing just below the translatable top cover, the fixed panel having openings at the positions of the gears allowing the gears to engage gear racks through the panel. In some cases the fixed panel may be transparent in at least the portion visible with the translatable top cover retracted. In this case there is a light-emitting device visible through the transparent portion of the fixed panel, the device changing color with data transfer.
In one embodiment of the invention a thumb drive has a manually extendable and retractable male USB connector.
Drive 101 has in this example a physical opening 102 generally rectangular in shape, matching the rectangular cross section of a male USB connector. Port 102 is closed, when the connector is withdrawn within a body of the thumb drive, by a retractable physical closure, such as a flap gate 103, which may be hinge mounted in one embodiment to allow passage of a male USB connector.
It will be apparent to the skilled artisan that there are a variety of ways a closure may be implemented for opening 102. Such a closure may be made of a number of different materials, such as rubber or plastic materials, and may be implemented in a number of different ways. For example, the gate could be a solid metal or rigid plastic material, and a mechanism for opening and closing may be provided also in a number of different ways.
Further to the above description, a sliding button 104 is implemented through an opening in a wall of a case for the drive. This button in one embodiment has two functions. Firstly the button is implemented in a manner to turn on a flashlight element 105 when the button is depressed. Secondly, the button is detented in a way that when depressed it may be pushed forward, causing an internal mechanism to translate forward, urging a male USB connector to extend through port 102, and to lock in place as extended. The locking in place in one embodiment is a function of the detenting of the button mechanism.
It will also be apparent to the skilled artisan that such a manual operator for translation of a mechanism to extend the male connector through opening 102 may be implemented in several ways as well, such as by a knob or a slide. In one embodiment, for example, the retractable connector is spring-loaded into the case of the thumb drive with a detent for keeping it retracted until a user trips the detent. A similar detent keeps the connector in an extended position until the user pushes the connector back into the case.
Light 105 in one embodiment is offset to one side of the thumb drive as shown, and is provided for aiding in finding a USB port on a candidate computer. The light may also be used as a utility flashlight for a number of other purposes. The skilled artisan will understand that there are a variety of ways control for the light may be provided in addition to the slide button 104, such as by a separate switch implemented through the body of the thumb drive.
The internal flash memory of module 301 is coupled to I/O contacts of a USB male connector 305 which is built into module 301. Internal connections, microprocessor, and firmware applying the microprocessor to functions of the apparatus are not shown, but will be apparent to those with skill in the art, as these mostly exist in the commercial arena at the time of filing the present application.
Module 301 in this an some other embodiments is implemented within the shell of portions 213 and 214 restrained between molded-in tracks, such that the module may be translated from a position wherein USB male connector 305 is fully withdrawn, to a position wherein the USB connector is fully extended, and back again. Detents molded into upper portion 213 in conjunction with opening 210 provide for retention at the fully withdrawn and near the fully extended positions, in concert with depressing button 211. To extend or withdraw one may depress button 211 and release it at the end of the movement. When USB connector 305 extends, door 212 is urged aside in a manner that when the USB connector is again withdrawn, the door closes again.
To move the connector forward, that is, to extend the connector, a user depresses button 211 such that land 312 of the button is below land 310 of edge 306. This depressing of button 211 makes electrical contact turning on light 216. Now module 301 may be moved forward by urging button 211 forward to extend USB connector 305. Land 310 ensures that the light stays on if the button is released.
Land 308 allows the user to move connector 305 to a maximum forward position, passing land 309, at which point the light will stay lit. This allows for the user to release the button while looking for a female USB port for connection, and keeps the light on.
When the female USB port is found and male connector 305 is inserted, the action of insertion will retract the male connector in the thumb drive until the spring-loaded button clicks up to land 309, providing a detent near the fully extended poison with the light off and the thumb drive connected to the appliance having the female USB port.
The skilled artisan will be aware that the detent mechanisms described above with reference to
